NUMBEBING'STAHP FOR PHOTOGRAPH'VIC-PRINTING"MACHEN ES.

Application led March 5, 1925.

This invention relatesto photography, and more particularly to photogra hic printing machine numbering stamps. ne object of my invention is to provide a simple linkage for moving the numbering stamp in timed relation to the platen, and to and from an ink pad carried'by the platen. Another 0bjectfis to provide a printing machine stamp which may bereadily cleaned and adjusted. Another objeiztisto1 provide a stamp which may be pivoted directly t0 the printing machine frame and whichv may be operated through a'. single link connected to the platen moving'4 mechanism. Another object is tol provide a latch mechanismthrough Which the stump maybe moved together with or independentlyof the platen, and other objects Will appear hereinafter from the following; specification, the novel `features f ing,.- pointed otitin,I the claimsl at1 the' end theife'f.

This printing,stampisy an improvement over the stampj l shown.l in my copeniding pat ent application for numbering stamp; for photographie printingl machines,- Serial No. 756,348, filed December 16, 1924, and ispar tiemlarly ad'a]g tedl forL use;l on the printing machine shown inxnycopending patenty applieation Seriali No; {5G-,347, photographic printing machine, filedl December16,l924.

Coming. now to the drawings` wherein like reference charaeters denote like,v parts throughout: l Fig.- 1v isa yside elevation showing a portion of a printingA machine in section, equipped with a numbering stamp'y construct-ed in accordancewithf and illustrating one forxnv of my infvention Fig. 2 is a longitudinal section through the stamp carrier showing a'nfelevatlon of the stamp;

Fig. 3 is-an end'elevation of the stamp and carrier; and

Fig.y 4 is aplan viefw ofthe stamp andlcarrier removed from afprnter.

I have shown my printing'lstamp by Way of illustration asmountedvupon a printing lnaohinefoflthe type shown yin my copending alpplicationabovereferred to. Thisprinter mayI consist of a' top 1f which supports a bifaeketa2 at the'back'andafprintingipanel 3 in the printer top. This` panel 'may be coverlby meu-nsof a platen 4 which is pro- Serial No. 13,239.

vided with a rearwardlyV extending arms 5 pivoted at 6 to lugs 7` extending up from the printer top. The'platen maybe moved by means of a handle 8 which is on the endfof ai' lever 9 which forms one arm of a bell crank lever pivoted'at lOyto the platen, and having a second arm=11 pivoted at 12 to an upper'link y13. Link 13 iscarriedby the shaft 14 which is supported by the bracket A2. Links lland 13 kform a toggle Whichmay exert resilient` pressure upon the platen fl througlrthe spring support 15.

There is an aperti'uel cut in theplaten through which a printing stamp 17 may operate to impress itscharacters :upon yprint,- ing ypaper supported by the printing4 panel y3. This stamp may lbefo'li anyy prefferred type, andlis here'sh'ownas consisting-.of a casing 18 carrying'va pluralityofl typediscs 19 which may bemoved by-meansof an operating handle. 20. .f A y T he-stanrp is supportedin a stamp carrier 21', which `is preferablyy channel V.shaped havingsides'22 inoneendof which 23 Iare" apertures 24 which forma bearingvforl a. shaft25 'which hingedly se'euresthe stamp carrier to the table `1 through theupstanding lugs 26. At the opposite fend of the 'sides 22 there are extensions V29, each'h'aving apair ofislots 2 through which pins 28 attached to the stamp casing 18 may slide. The stampis normally pressed downwardly by means ofa spring 3()y Whichl isattached insidek the channel member againstv the'top 21 by means of a bolt.; 31. y

The stamp maybe movedabont its shaft 25-byy means of the followingmechanisin': an arm 32, asis best shown-in-Fig. 2, is pro'- vided with a flat`A Surface 33, this surface beingrivetedat 34 toa block 35 which may be in the form of a casting having an up- Wardly extending hook 36.y This hook passes freely through a cut-out portion* 37 in the `top21foif'thechannel member.A It may, yhowever, be held tightly by means of a latch-38 which ispivoted upon`stud-31, and which is provided with an4 operating handle 39. VVlienportion 40 liesV beneath the hook," as is shown in the drawings, arm`32 in effect is integral y with the stamp, carrier, but, when thel locking disc 38 is turned'in the direction of the arrow, Fig. l',-portion41 of the. disc comes oppositethe hook, thus permitting the arm 3' to separate 'from the stamp carrier so that the integral relation is broken.

i-irm 3Q pivoted on a stud i2 which is carrier b v an arm -fl'l which is pivoted at -ll to vthe toggle rl`his comiection causes the stamp carrier and platen to be mover simultaneously when the han-'le S is moved. In the full line positions in Fig. l, the parts are in their operative position, in which the printI paper is being` held against the i, panel by the platen. In this position, tire stamp has been moved through the cpeni` g lo in the platen, and the type discs i9 nay rest against the printing paper. The dashed line positions in this ligure, indicate the inoperative position oi tle parts in which lhn s1 imp discs 'i9 rest against an inking o. is carried upon a bracket 50 '-.ttached by a screw 5l to the platen Il. As the handle 8 moved, the stamp carrier and the platen swing about their offset pivots G and 2', so that the stamp is inked at one eX- tremity or" the movement, and the stamp will rest against the printing paper at the other extremity ot movement.

The operation of my device is as follows: the handle 39 may be moved in the direction shown by the arrow in Fig. Ll, to release the latch so that tie carrier may be swung up as -far as necessary, as indicated in broken lines, Fig. 2, so as to clean or adjust the stamp discs i9. The carrier may be then swung back and engagea with the link 32 through the latch 38. By raising the handle 8 to move the platen l from the printing panel 3, link 43 through toggle member 13 causes the stamp carrier to swing about its pivot 25 into contact with the inking pad 49 carried by the platen 4. The printing material may be then adjusted on the platen 3, and the handle 8 lowered, thus bringing the platen 4: against the printing material, this causes a reverse movement ot the toggle members 11 and 18, and through link 43 the stamp carrier is moved towards the printing pane-l so that the type discs 19 will pass through aperture 16 and a spring 30 will cause the stamp 17 to exert a light pressure upon the printpanel. rlhe width between the supportarms 27 tor the stamp is preferably a litgreater than the thickness or the stamp 17, so that the tour pins and slots 27 and 28 permit a slight universal movement of the stamp, although the spring SO also exerts a downward pressure upon the center of the stamp, thus causing a tirm ancl even impression to be made.

Vhile I have described my printing stamp mechanism as particularly useful with a printing machine of the ty 3e above described, certain features of my invention are applicable to diii'erent types ot machines, and I contemplate as within the scope ot my invention all such modiiications may come within the scope of the appended claims.
